Starting today, Opera developer has been doing nothing but freezing up. It worked yesterday and briefly this morning, but now it is not working at all. I tried rebooting my computer and disabling my antivirus with no success. I have no idea what is wrong and I wish I knew the reason why. Now, I am getting nothing but Opera is unresponsive, relaunch now? messages instead.
That's the thing with dev/beta builds. Nobody guarantees they'll work, because the devs are pushing them out as fast as they can code new features, so they don't have time to test stuff. For example, the Chromium continuous build waterfall (as in a new build being pushed out every 10 mins.) is compiled from the latest code in the chromium repository, and as a result, is very buggy. Have you tried using a normal build?
